Abstract：A new heterometal complex [Mg(H2O)6][Zn(pydc)2]·2H2O (1， H2pydc＝pyridine-2,5-dicarboxylic acid) was synthesized by hydrothermal reaction of pyridine-2， 5-dicarboxylic acid with MgCl2·6H2O and Zn(NO3)2·6H2O at 120℃ for 3 days. The complexes were characterized by X-ray single crystal diffraction， X-ray powder diffraction， infrared spectroscopy， thermal stability analysis and room temperature solid-state fluorescence spectroscopy. The results showed that the complex crystallizes in triclinic system， space group P， and the cell parameters are as follow： a＝0.72725(10) nm， b＝0.74311(10) nm， c＝1.06859(15) nm， α＝78.968(2)°， β＝74.332(2)°， γ＝70.428(2)°； V＝0.52066(12) nm3， Z＝1. The complex exhibits dark-blue fluorescence.
